NPC Script with Functions not working - invisible/not on a map error

[latheesan 15]

Hi everyone,

 

I've been away from Ragnarok Online for a very long time, I have recently picked it up and I have started NPC Scripting again.

 

I am working on a daily reward script that uses function and I am getting this error: invisible/not on a map error

 

I have managed to re-produce the error with this test script:

 

// Main Script-	script	L_Test	-1,{		// When script starts	OnInit:			// Configuration		set .npc$,"[ Test NPC ] : ";	end;		// When player logins into game	OnPCLoginEvent:			dispbottom(.npc$ + callfunc(L_SayHello, strcharinfo(0)));		end;	}function	script	L_SayHello	{	set .playerName$,getarg(0);	return "Hello "+ .playerName$;}

This script structure is identical to my real script. So when I start the server and login, I get the following error in map server:

 

[Warning]: Unexpected type for argument 1. Expected string.[Debug]: Data: variable name='L_SayHello' index=0[Debug]: Function: callfunc[Debug]: Source (NPC): L_Test (invisible/not on a map)[Error]: script:callfunc: function not found! [0][Debug]: Source (NPC): L_Test (invisible/not on a map)

Any idea what this error is about?

The function needs to be in "", you also should use = instead of set. You also don't need to pass strcharinfo, you can call it in your function.

// Main Script-	script	L_Test	-1,{	// When script starts	OnInit:		// Configuration		set .npc$,"[ Test NPC ] : ";	end;		// When player logins into game	OnPCLoginEvent:		dispbottom( .npc$ + callfunc( "L_SayHello" ) );	end;}function	script	L_SayHello	{	return "Hello "+ strcharinfo( 0 );}

did you specify where the NPC is located on the script?

 

ex: prontera,150,150,5 script  NPC NAME    NPC_ID,{
